Database Trigger:
In the Design Editor: Menu "Generate Database from Server Model" in the "Generate" menu.
Select the table containing the trigger desired and generate the DDL files (select only Triggers in the options dialog). A few files will be generated, and one of them contains the trigger.

Forms Trigger:
In the node "Application Logic" of the Module tree, you can add your triggers. When you generate the Form, make sure the application logic is generated too (in our version (6.0), it is a checkbox that needs to be cleared ("Ignore user Application Logic").
